SPECIFICATION forming part of Letters Patent No. 396,087, dated January 15, 1889.

Application filed July 11, 1888.

T0 aZZ whom it may concern.-

Be it known that I, HARRY IIOLLOWELL, a citizen of the United States, residing at Longville, in the county of Jefferson and State of Pennsylvania, have invented certain new and useful Improvements in Stump-Extractors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in stump-extractors; and it has for its objects to provide an improved lever and vertical bar, in combination therewith and operated thereby, whereby a powerful strain may be brought to bear upon the stump, so as to gradually draw the same from the ground, as more fully hereinafter explained.

The above-mentioned objects I attain by the means illustrated in the accompanying drawings, in which- Figure 1 represents a perspective view of my improved stump-extractor set up and ready for use, one of the legs being indicated in dotted lines; Fig. 2, adetached side elevation of the lever, and Fig. 3 is a detached perspective view of one of the pins used in connection with the lever and bar.

Referring to the drawings, the letter A indicates a lever, which is fulcrumed midway between its ends to the lower ends of a bifurcated hanger, B, which is removably secured to the upper connected ends of a tripod, C, by means of a link, D, which sets over said ends so as to support the lever at the proper height directly over the stump to be extracted. The lever is constructed of two side plates, at, of metal, between the ends of which are placed the tangs l), to which the plates a are securely riveted, leaving a recess extending through the lever, through which the vertical bar D passes freely. The lever is strengthened on both sides by the fulm'um-plates c, which are secured by the same rivets by which the plates (t and tangs b are secured, the said plates being bent midway between their ends so as to form recesses between the said plates a and c, in which thelowerends of the hanger to which the lever is fulcrumed extend, as

shown in the drawings. The upper edges of Serial No. 279,657. (No model.)

the plates a at each side of the fulcrum of the lever are provided with semicircular recesses (Z. The bar D is provided with a series of apertures, e, at its opposite sides, the series at each side being equidistant from each other, and those of the opposite sides alternating with each other, for the purpose hereinafter described. These apertures e are for the reception of the detachable arms E, which are provided with short projections g, which e11- ter the apertures in the bar D, the projections resting in the recesses d, the curved portions of the arms resting upon the upper edge of the lever. The lower end of the vertical bar has secured to it, by means of a suitable link, I), a plate, E, having recessed shoulders at each side, around which the chain Z) embracing the stump may be passed and secured.

The letter G represents the detachable handles, which are provided with sockets at one end, so that they maybe titted upon the tangs of the lever when the extractor is in use and removed when not in use.

Having described the construction of myinvention, I will now describe its operation.

The tripod 0 being set up and the parts all secured in position, as shown in liig. 1, with the shouldered plate at the lower end of the vertical bar I), secured to the chain embracing the stump, the said bar is drawn upward through the recess in the lever until it tightens upon the chain, the lever being inclined to one side. One of the detachable arms before mentioned is then inserted in the lowest aperture exposed above the upper edge of the lever on the depressed side thereof, with its curved arm resting against the upper edge of the lever. The lever is then operated by means of the handle to elevate the depressed side and depress the opposite side. This action. raises the vertical bar D, so as to expose the aperture on the opposite side of the same and next below the one in which the removable arm before mentioned is inserted. A similar arm is then inserted in the aperture thus exposed, after which that side of the lever is elevated, raising the'vertical bar again and depressing the opposite end of the lever, so as to expose another aperture on that side of the lever, when the detachable arm above itis removed and placed in the aperture eX- posed and the operation repeahid. This operation is continued, raising the he r I) by sue eessive steps, until the stump is gradually drawn out of the ground.

The various parts of my improved stumpextraetor heing' detachable, they may be packed in small compass t'or trz'insportntion, which is a decided zulvuntnge.

I wish it to he understood that I do notliniit 1n yselt' to the precise construction of parts as shown in my drawings and heretofore described, hut reserve to myself the right to viirytu'iy of said parts or substitute others [or the better (jflllylllg out oi my invention without ('lepurtine' [from the essential IH'lllClplG thereof.

\Vlmi I claim, and desire to secure h v Letiers Patent, is

l. The mnnhinniion, with the lever A and its hanger B, and the perforated bar D, having link b, and shouldered plate E, of the arms E, halving projections g, adapted to be secured in the 1 erforations e andheara gainst the upper edge of the lever in the curved recesses (I, substantiallyas and for the purpose specified.

2. The comhinatioinwitli the lever A and its hanger 3, of the fuler1n'n.-plates a, secured to the lever at each side and forming recesses, Wherein the ends of the hunger to which the lever is fulcrunied extend, substantially as shown and described.

In testimony whereof I nt'i'ix my signature in presence of two witnesses.
